No not really. The two boxes in question there are sealed units. In fact both were designed to simply be placed on an engine compartment firewall etc. Having a little fresh, cooler air rolling across them will be a plus, a little dusty or not. We did not do a lot this weekend on the car, I made a knockout list of final little things that we need to get done to call it "complete"...or at least for now! LOL 1. Install the passenger side roof hold down strap and adjust both sides etc 2. Install wrap around seat belts 3. Two small final pieces of carpet on driver's side (around the wheel well tub area) 4. Lexan rear window installed on the top 5. Install some kind of insulation on the underside of battery box lid to avoid contact 6. Mesh wire loom the front lights wiring harness 7. Re-bleed the front brakes 8. Driver's side only cowl area fire and weather seal 9. Install the customized escutcheon rings on the roll bar through body areas (4) 10. Figure out somewhere and or how to mount the rear view mirror 11. Finish the exhaust system (which I have all the pieces but I am in no hurry to do) 12. Install Doors, Hood and Trunk seals which I have the material for etc. 13. Fabricate some kind of inner wheel well cover for tail lights, they are simply exposed in there 14. Mount the Cold Fire Extinguisher 15. Install Roll cage padding in a few choice spots 16. Install a one way valve on my fuel cell vent tube We did mange knock to the first one off the list this weekend and the roof is down and ready to roll. I also modified the hooks on the end of the hold down straps so they are sort of a quick release. Very easy to drop the tension levers and unhook allowing the roof to flip up and open. I am fairly excited about the knock out list at this point. None of them are more than a few minutes worth of work and now there are only 15. I can remember several lists that I simply gave up writing things down after 100 entry. LMAO!
